WPE and wow cheat

i heard a post about using WPE and hacking wow creating a filter in colum 28 using value 01 and changing to 00...this was suposed to bypass the paying part of the buying process unfortunatly all i managed to do was crash my wow

i leave the link where i saw this for more info
Does this work on wowgasm? Does it work at ALL

So plz tell if you know this cheat actually works or any other like or a *** mode cheat or 1hit kill for wow

Thank you very much and sorry that i can't post a german version of this
